Fish Species Suitable for Aquaponics System

Aquaponics techniques have gotten an increasing number of common as additions to permaculture gardens. The truth is, they’re changing into more and more essential within the wrestle to create extra environment friendly and inexperienced strategies of manufacturing meals.

Crustaceans There are a variety of crustacean species that may be utilized in an aquaponics system, both as a standalone or together with fish species. Freshwater prawns, crayfish and mussels are all viable choices.
